<p>#CMT# #/CMT# The device has a guide device (14) extending along a travel path of a material web. An inlet-side nozzle device (15) and an outlet-side nozzle device (18) have nozzles (16, 37) i.e. open jet nozzles, for two types of gas flow, where one of the gas flow runs against conveying direction of the material web, and the other gas flow runs along the conveying direction. One of the nozzles is formed as nozzle tubes, and generates flow fields that are partially aligned in different manner. The nozzles are externally arranged in an array line in angular manner. #CMT#USE : #/CMT# Device for transferring an edge strip of a web e.g. material web (claimed) such as paper web, in a station of a web production or processing machine e.g. paper machine, paperboard machine and fabric- or fiber machine. #CMT#ADVANTAGE : #/CMT# The nozzle is formed as the nozzle tubes, and generates the flow fields that are partially aligned in different manner, thus constructing the transferring device with improved efficiency in a simple manner, improving random behavior of the jets of nozzle series for formation of an air carpet, eliminating hazard of tear of the air carpet at the end of the air guide device, designing robust and maintenance-free device, and reducing consumption of foaming agent. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of an air guide device for producing gas flow by a nozzle device. 14 : Guide device 15 : Inlet-side nozzle device 16, 37 : Nozzles 18 : Outlet-side nozzle device 36 : Supply tube.</p> |
